current version of this list can be found at the url above. Several of these
units need addional attributes or definition. These are commonly-used units in
oceanography and limnology.

Changing QA contact to the list for all current EML bugs so that people can
track what is happening.

Not adding: einsteins; recommendation is to use moles instead.
added irradiance and spectral irradiance units in watts, also for solid angles. eg
wattPerMeterSquaredPerSteradian, wattPerMeterSquaredPerNanometer
(common ones from optics instruments only. a person could go nuts with these)

added

  • permil (analog to percent)

a few more concentration units:

  • mmol per meter cubed
  • micro, milli and Equivalents per Liter (conductivity in water)
  • siemens per cm

and some primary production units (gotta have 'em):
milligramPerMeterCubedPerDay
milligramPerMeterSquaredPerDay
these are for aquatic; the terrestrial units were already there.

TO DO: units are all added, but don't close till you review the descriptions. still finding copy-paste cruft.
